   I. – The provisions of this section apply to the establishments mentioned in Article L. 231-1, in compliance with the principles set out in Article L. 1333-1 of the Public Health Code, provided that workers are likely to be exposed to a risk due to ionizing radiation:
   – resulting from nuclear activities subject to an authorization or declaration system in application of article L. 1333-4 of the public health code;
   – occurring during interventions mentioned in article L. 1331-1 of the public health code carried out in a radiological emergency or resulting from long-term exposure to ionizing radiation, as defined in application of 3 ° of the article L. 1333-17 of the same code.

   II. – The provisions of subsection 7 are applicable to the establishments mentioned in article L. 231-1 when the presence in the workplace of natural radioelements, not used for their radioactive properties, leads to a significant increase in exposure workers, compared to the natural level of radiation, likely to endanger their health.

   III. – The provisions of this section apply to any self-employed worker, in accordance with the terms set out in III of article R. 231-74, when there is, for himself or for other persons, a risk of exposure mentioned in I or II of this article.

   IV. – However, the provisions of this section do not apply to exposures resulting from radionuclides naturally contained in the human body, cosmic radiation prevailing at ground level or radiation resulting from radionuclides present in the undisturbed earth crust.

Article R231-74

(inserted by Decree n ° 2003-296 of March 31, 2003 art. 1 Official Journal of April 2, 2003)

   I. – The head of the establishment takes the general administrative and technical measures, in particular in terms of work organization and working conditions, necessary to ensure the prevention of occupational accidents and occupational diseases likely to be caused by exposure to ionizing radiation resulting from the activities or interventions mentioned in I of article R. 231-73.
   II. – When the head of the user company brings in an outside company or a self-employed worker, he ensures the general coordination of the preventive measures he takes and those taken by the head of the outside company or the self-employed worker , in accordance with the provisions of Articles R. 237-1 et seq. To this end, the head of the user company communicates to the person or department responsible for radiation protection, mentioned in article R. 231-106, the information transmitted to him by the heads of external companies in application of the article R. 237-4. It transmits the specific instructions applicable to radiation protection in the
   Each company manager is responsible for applying the preventive measures necessary for the protection of his staff and, in particular, for the supply, maintenance and control of personal protective devices and equipment and measuring instruments. of the individual exhibition.
   Agreements can be concluded between the head of establishment and the heads of outside companies or self-employed workers concerning the provision of personal protective devices and equipment as well as instruments for measuring individual exposure.
   III. – The self-employed person carrying out an activity referred to in III of article R. 231-73 implements protective measures vis-à-vis himself and other people likely to be exposed to ionizing radiation by his activity. To this end, he takes the necessary steps to be medically monitored.

Article R231-75

(inserted by Decree n ° 2003-296 of March 31, 2003 art. 1 Official Journal of April 2, 2003)

   I. – Individual and collective occupational exposure to ionizing radiation must be kept below the limits prescribed by the provisions of this section at the lowest level that is reasonably possible.
   II. – To this end, the head of the establishment carries out an analysis of the workstations which is renewed periodically and on the occasion of any modification of the conditions which may affect the health and safety of workers.
   In particular, during an operation taking place in the controlled area defined in article R. 231-81, the head of the establishment, in collaboration, if necessary, with the head of the establishment of the external company or the self-employed worker:
   – arranges for a forecast assessment of the collective dose and the individual doses that workers are likely to receive during the operation. To this end, he has the person competent in radiation protection, appointed in application of article R. 231-106, define beforehand collective and individual dose objectives for the operation. To this end, those responsible for the operation provide assistance to the competent person. These objectives are set at the lowest possible level taking into account the state of the art and the nature of the operation to be carried out and, in any case, at a level not exceeding the annual limit values ​​set in Articles R 231-76 and R. 231-77;
   – has the radiation doses actually received during the operation measured and analyzed in order to take measures ensuring compliance with the radiation protection principles set out in Article L. 1333-1 of the Public Health Code. When the technique permits, these measurements are carried out continuously to allow immediate reading of their results.

Article R231-76

(inserted by Decree n ° 2003-296 of March 31, 2003 art. 1 Official Journal of April 2, 2003)

   I. – The sum of the effective doses received by external and internal exposure must not exceed 20 mSv over twelve consecutive months.
   II. – The equivalent dose limits for the different parts of the body exposed are as follows:
   – for the hands, forearms, feet and ankles the exposure received during twelve consecutive months must not exceed 500 mSv;
   – for the skin, the exposure received during twelve consecutive months must not exceed 500 mSv. This limit applies to the average dose over any area of ​​1 cm2, regardless of the exposed area;
   – for the lens of the eye, the exposure received during twelve consecutive months must not exceed 150 mSv.

Article R231-77

(inserted by Decree n ° 2003-296 of March 31, 2003 art. 1 Official Journal of April 2, 2003)

   I. – In the event of pregnancy, measures are taken so that the exposure, in her employment, of the pregnant woman is such that the exposure of the unborn child, during the time which elapses between the declaration of pregnancy and the time of delivery, is as low as reasonably possible, and in any event below 1 mSv.
   II. – Breast-feeding women must not be assigned or kept in workstations involving a risk of internal exposure.
   III. – Persons aged sixteen to eighteen authorized during their training, under the conditions provided for in article R. 234-22, to be employed in work exposing them to ionizing radiation may not receive during twelve months consecutive an effective dose greater than 6 mSv or equivalent doses greater than the following values:
